class Statement

SQLite implementation of \Drupal\Core\Database\Statement.

The PDO SQLite driver only closes SELECT statements when the PDOStatement destructor is called and SQLite does not allow data change (INSERT, UPDATE etc) on a table which has open SELECT statements. This is a user-space mock of PDOStatement that buffers all the data and doesn't have those limitations.
